The Curtiss Flying Boat
On January 12, 1912, Curtiss developed a utility flying boat that he sold to the U.S., Russian and Italian navies. The following year he designated these as the Model F series aircraft, some having transatlantic capabilities. The first Model F saw service with the United States Navy, having the designations C-2 through C-5. These aircraft were later reclassified to AB-2 through AB-5. In October of 1913, Curtiss met John Cyril Porte, a British pioneer in aviation who shared his interest in flying boats and helped design the improved Model F-5-L flying boat. These aircraft became known as “Seagulls” in the postwar civilian market.
